Chimney fire grows to 3-alarms at Skywalker Ranch

A reported chimney fire grew to a three-alarm incident Tuesday night at the Skywalker Ranch off Lucas Valley Road.

The fire was reported shortly after 5:30 p.m. in the 50,000-square-foot "Main House," an office building on the property near Nicasio, firefighters said.

The private Skywalker fire crew called for help from the Marin County Fire Department, which called for backup firefighters from San Rafael. No one was injured, said county fire Battalion Chief Mike Giannini. The cause was under investigation, but Giannini said the fire apparently started in the area of a fireplace.

The fire caused "little to no damage," said Emilie Nicks, spokeswoman for Lucasfilm, which owns three properties on 6,100 acres in the area.
